definition:
Seer - 'one who sees the future' First in the audio chain after
the source the Seer 'sees' all that will be heard and conveys its
musical truth. The Seer offers the enthusiast a high standard
compact and versatile all tube preamplifier.
Seer Line
- with five inputs, as a line-level only model The line stage is
designed using similar circuitry techniques employed by its two
box counterpart the Prophet preamplifier, but utilizing a
different tube and a less exotic power supply. Each line channel
utilizes a low noise double triode operated in single ended class
A. With a minimum of coupling components between stages the
circuit achieves a very wide bandwidth of 5 Hz to 115kHz,
providing admirable results with high quality CD players.
The non-buffered output is suitable for
driving medium lengths of inter-connects giving meritorious
results in systems where the Seer would be the sole tube amplifier
component, conveying a natural musical tonal balance to ones
system, especially popular used with solid-state power amplifiers.
All inputs are hard wired for maximum signal transfer and high
quality gold plated RCA phono sockets are mounted on a
non-magnetic back-panel for minimum interference. All circuitry is
mounted on a double sided 3/32 fibreglass pcb with 3oz copper
tracks and combining elegant circuit layout and high quality
components such as gold plated tube bases 1% tolerance metal film
resistors and polypropylene capacitors,
the Seer presents music with excellent clarity unusual for tube
preamplifiers in this price range.
The power supply incorporates a high quality potted toroidal power
transformer together with a solid state regulated heater supply
and hum filtered high tension supply. This low noise supply allows
the Seer to work at maximum gain with an absence of background
noise especially useful when listening
to the phono input. All the electronics are housed in a fully
screened chassis and to compliment its elegant lines the front
panel is machined from solid 6mm aluminium billet with a brushed
anodised finish.
Il finale Unisis
The Unisis was developed in 1990
by Tube Technology and even after fifteen years it is still a much
sought after amplifier, combining the classic virtues of tube
amplifier design with the modern 'clean' power delivery often only found
in higher power designs. It has often been imitated by other
manufacturers but never equalled.
The Unisis Signature is a vast improvement over its famous
predecessor. It features a new high current driver stage, uprated
power supply and best of all a superb new output transformer which
has been in development over the last two years. Other
major improvements are individual output tube protection and
outboard bias meter acceptability, allowing easier maintenance of
the output tubes.
All of these improvements add up to a formidable amplifying
system, with improved bass performance and amazing control and
presence for an amplifier of this power rating, we believe you
will be delighted with the speed, delicacy and openness of this
exceptionally beautiful power-house.
Power is delivered into the most difficult of loads including
electrostatic speakers, which make most solid-state designs curl
up their toes. This neat package will take pride of place in your
listening room and become the centre of the most ambitious of
hi-fi systems where high power output is not of paramount
importance. The chassis is hand-crafted from sixteen gauge
non-magnetic high purity stainless steel.
All signal paths are hard wired with PCOCC and silver cables and
kept to a minimum length. Inputs for are through high quality gold
plated RCA phono sockets and outputs through a high quality pair
of gold plated 4mm binding posts for each channel. The power
amplifier section employs the EL84 output tube, the smaller
brother of the EL34 as used in the Genetix and Synergy. This tube
has a very fluid and crisp sound which injects exciting realism
into a music performance.
The new and improved output transformers are designed to our proprietary
design and each transformer is painstakingly hand wound to our
exacting specifications. The output transformer is the most
important component in a tube amplifier and our obsession for
getting this right is even relayed in the manufacturing process,
where during winding inductance measurements are taken for extra
precision and consistency.
The power and preamplifier printed circuit boards are through
plated 3/32 fibreglass, three ounce copper fitted with silver
contact ceramic tube bases and component quality is carefully
selected for both musicality and reliability, including 1% metal
metal film resistors, polypropylene capacitors and long life low
impedance custom power supply capacitors. The Unisis Power may be
switched from a Stereo 35 Watt
amplifier to a mono 70 watt amplifier, so is very useful for
either bi-ampling or mono-blocking if higher power requirements
are needed for more hungry loudspeakers.

Lo strumento per eseguire la regolazione
bias
Accoppiata davvero eccellente ,
piacevolissima , sopratutto per chi ama questa valvola che risulta
sempre dolce e leggermente frizzante. I 35 watt sono
più che sufficienti per pilotare la maggior parte dei diffusori
commerciali con ottimi risultati.
